2 Claims.

The ordinary gasoline stand is provided with a meter, a motor and a pump driven by the motor driving the gasoline through the meter to a service hose from which it is delivered to the car of the customer. It is desirable to stop the pump at the completion of the filling operation and this has heretofore been accomplished by providing the hook on which the nozzle of the hose is usually hung with means actuated by the weight of the nozzle for opening the switch of the controlling motor. This does not fully satisfy the requirements in two respects, first, the interval between the service and the closing is greater than is desirable, and, second, if through any carelessness the operator does not hang up the hose the motor continues to run forcing the gasoline against the closure valve at the nozzle.

With the present invention the control of the switch is taken care of by a movement of the hose in service. Preferably this is accomplished by a pull on the hose by the operator as he holds the hose ready for service. Features and details of the invention will appear from the specificatlon and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows:

Fig. 1 shows a side elevation, partly in section, on the line I--I in Fig. 2.

Fig. 2 a section on the line 2--2 in Fig. 1.

I marks the stand. A motor 2 is mounted in the stand driving the pump shaft 3 which actuates a pump 4. Gasoline is delivered to the pump through a pipe 4a and discharged through a pipe 5 to a meter 6, an indicator I indicating the flow. The gasoline flows from the meter through a pipe 8 to a service hose 9.

A switch I controls the motor. A lever II is the active element of the switch throwing a switch stem Ila. A spring I2 operates on the lever and closes the switch.

A nozzle support I3 is ordinarily in the form of a forked hook adapted to receive a nozzle I3a. The support is pivotally mounted on a pin I4 carried by the stand and has a lever extension I la. A rod I is hooked into a perforation I6 in the extension Ma, the opposite end of the rod being hooked into a perforation I! on the bell crank lever II. If the spring I2 should become damaged, or fail to open the switch the weight of the nozzle on the support I3 operating through the lever extension and rod I5 supplement the spring in effecting the opening of the switch when the nozzle is hung on the support.

A flexible connection, preferably in the form of 1930, Serial No. 478,864

a wire cord I8 is secured on the lever II and extends through a bushing I8a in the stand. The end of the cord is secured in an ear I9 extending from a ring 29. The ring 20 is arranged around the service hose 9 a short distance below its connection with the discharge pipe 8. The bushing I812 has a flaring opening so that the flexible cord, or connection I8 may be drawn by side movement of the hose either directly in line with the cord I8, or in a direction forward and back, the rounded portion of the bushing easing the movement of the cord in these pulls at an angle.

In use the operator unhooks the nozzle. The switch remains open with this removal. He then carries the nozzle to the supply tank, or other receptacle which it is intended to fill. Ordinarily the operator holds the hose in this operation. When in position for filling the operator exerts a pull on the hose and this acting through the connection closes the switch and starts the pump. The pump continues to operate so long as the operator exerts this pull. As soon as the pressure on the hose is released the spring I2 operates and opens the switch. In this manner the starting of the pump is practically coincident with the starting of the filling action and the stopping of the pump is practically coincident with the cessation of the service operation through the hose.

What I claim as new is:-

1. In a liquid dispensing apparatus, the combination with a stationary pump stand; of a. liquid dispensing pump in said stand; an electric motor in said stand, operatively connected with said pump; a liquid discharge conduit in communication with said pump and including a flexible hose; an electric switch for controlling the energizing circuit of said motor; means cooperatively connecting said flexible hose with said switch, including a flexible connector extending through said wall of said pump stand and having one end connected with said hose; whereby said switch may be closed to operate said pump, by the operator flexing said hose to position for a dispensing operation; a spring for automatically opening said switch and stopping said pump when said hose is released; a movable hose support on said stand; and means connecting said hose support with said switch; for holding the latter open by said support; whereby, said switch is held open when said hose is held by said support.

2. In a liquid dispensing apparatus, the combination with a stationary pump stand; of a liquid dispensing pump in said stand; an electric motor in said stand operatively connected with said pump; a liquid discharge conduit in communication with said pump and including a flexible hose; an electric switch adapted to control the energizing circuit of said motor; means cooperatively connecting said flexible hose with said switch; whereby said switch may be closed by movement of said hose; and a hose support fulcrumed in said stand and connected with said switch; whereby, when said hose is held on said support, said switch is prevented from being closed by movement of said hose.
